Mass Casualty Incident (MCI) training in a metropolitan university hospital: short-term experience with MAss Casualty SIMulation system MACSIM®

Exploring medical first responders' perceptions of mass casualty incident scenario training: a qualitative study on learning conditions and recommendations for improvement

OBJECTIVE

Despite participating in scenario training, many medical first responders (MFRs) perceive themselves as inadequately prepared to respond to mass casualty incidents (MCIs). The objective of this study was to conduct a comprehensive examination of traditional MCI scenario training methods, focusing on their inherent strengths and limitations. An investigation into the perceptions of MFRs who had participated in MCI scenario training was carried out to identify potential areas for improvement and provide recommendations for refining MCI training protocols.

DESIGN

Qualitative inductive approach using semistructured interviews that took place between October 2021 and February 2022. Data were analysed with qualitative content analysis.

SETTING

MCI scenario training involving four organisations (three emergency medical services and one search-and-rescue organisation) tasked with responding to MCIs, collectively representing four European Union countries.

PARTICIPANTS

27 MFRs (17 emergency medical services personnel and 10 search-and-rescue volunteers) were recruited to participate in the study.

RESULTS

Two categories and seven associated subcategories (shown in parentheses) were identified as influencing the learning outcomes for MFRs: Training in a context mirroring real-world incidents (conducting incident scene risk assessment, realistic representation in casualties, incorporating scenario variety into the curriculum, interagency collaboration, role alignment when training incident site management) and use of a pedagogical framework (allowing for mistakes, the importance of post-training evaluation).

CONCLUSIONS

This study reaffirms the value of traditional MCI scenario training and identifies areas for enhancement, advocating for realistic scenarios, interagency collaboration, improved incident site management skills and thorough post-training evaluation. It suggests a shift in MCI training conceptualisation and delivery. The potential of virtual reality technologies as a valuable addition to training methods is explored, with a note on the need for further research to ascertain the long-term effectiveness of these technologies. However, the selection of a training method should consider programme goals, target population and resources.

What If Nice Terrorist Attack Would Have Happened in Milan? Drawing a Disaster Plan for Mass Casualty Incidents Involving the Pediatric Population

Terrorist attacks involving children raised concern regarding the preparedness to treat pediatric trauma patients during mass casualty incidents (MCIs). The purpose of this project was to assess the resources available in Milan to respond to MCIs as the 2016 Bastille Day attack in Nice. Literature and guidelines were reviewed and minimal standard requirements of care of pediatric trauma patients in MCIs were identified. The hospitals that took part in the study were asked to answer a survey regarding their resource availability. An overall surge capability of 40-44 pediatric trauma patients was identified, distributed based on age and severity, hospital resources, and expertise. The findings showed that adult and pediatric hospitals should work in synergy with pediatric trauma centers, or offer an alternative if there is none, and should be included in disaster plans for MCIs. Simulations exercises need to be carried out to evaluate and validate the results.

Determining surgical surge capacity with a hybrid simulation exercise

Background

To help test and improve surgical surge capacity, mass casualty incident (MCI) exercises generate valuable information. Both large scale table-top exercises (TTX) and full-scale exercises (FSX) have limitations if you want to test an organisation's capability and structure. A hybrid exercise incorporating the advantages of TTX and FSX is a possible way forward, but is no standardised exercise method, yet. This study aims at evaluating the exercise results to determine the feasibility of a hybrid TTX/FSX exercise for an organization's capability and structure.

Methods

A hybrid MCI simulation using moulaged figurants and simulation cards was designed, where the emergency department of a level 1 trauma centre receives 103 casualties over 4 h. After registration and triage, all casualties are expected to be resuscitated in real time and are transferred for further treatment inside the hospital (radiology, operating theatres, intensive care unit (ICU)/postop and wards). When reaching operation theatre, ICU or ward, figurants are replaced by simulation cards. Observers ensured that those procedures performed were adequate and adhered to realistic times. Use of resources (materials, drugs etc.) were registered. Primary endpoint was average time spent in the emergency department, from time of arrival, to transfer out. Secondary endpoints were related to patient flow and avoidable fatalities.

Results

The hospital managed to deal with the flow of patients without collapse of existing systems. Operating theatres as well as ICU and ward beds were available at the end of the exercise. Several details in the hospital response were observed that had not been noticed during previous TTX.

Conclusion

FSX have a valuable role in training, equipping, exercising, and evaluating MCI management. Hybrid simulations combining both FSX and TTX may optimise resource utilisation and allow more frequent exercises with similar organisational benefit.

Major Incident Hospital Simulations in Hospital Based Health Care: A Scoping Review

Major incidents are occurring in increasing frequency, and place significant stress on existing health-care systems. Simulation is often used to evaluate and improve the capacity of health systems to respond to these incidents, although this is difficult to evaluate. A scoping review was performed, searching 2 databases (PubMed, CINAHL) following PRISMA guidelines. The eligibility criteria included studies addressing whole hospital simulation, published in English after 2000, and interventional or observational research. Exclusion criteria included studies limited to single departments or prehospital conditions, pure computer modelling and dissimilar health systems to Australia. After exclusions, 11 relevant studies were included. These studies assessed various types of simulation, from tabletop exercises to multihospital events, with various outcome measures. The studies were highly heterogenous and assessed as representing variable levels of evidence. In general, all articles had positive conclusions with respect to the use of major incidence simulations. Several benefits were identified, and areas of improvement for the future were highlighted. Benefits included improved understanding of existing Major Incident Response Plans and familiarity with the necessary paradigm shifts of resource management in such events. However, overall this scoping review was unable to make definitive conclusions due to a low level of evidence and lack of validated evaluation.

Use of simulation models when developing and testing hospital evacuation plans: a tool for improving emergency preparedness

BACKGROUND

In recent decades, analyses of hospitals evacuations have generated valuable knowledge. Unfortunately, these evacuation case studies often lack crucial details and policies that would be helpful in evacuation preparedness. The aim of this study was to use a simulation model to illustrate how it can aid emergency planners in the development, testing, and revising of hospitals evacuation plans. This study includes evacuation exercises at two emergency hospitals in Region Stockholm, Sweden.

METHODS

A scientifically validated simulation system for "table top" exercises was used for interactive training of hospital medical staff, prehospital staff and collaborating agencies. All participants acted in their usual professionals' roles. The exercises were run in real-time and mirrored actual hospital resources with the aid of moveable magnetic symbols illustrating patients, staff and transport, presented on whiteboards. During the exercises, observers and independent instructors documented actions taken and post-exercise surveys were conducted to obtain reactions and compare results.

RESULTS

The simulation system allowed the emergency planner to test the whole evacuation process, making it possible to train and evaluate the important functions of management, coordination, and communication. Post-exercise surveys explored participants perception of the exercises. Analysis of open-ended questions included areas for improvement and resulted in five main categories: (1) management and liaison; (2) communication; (3) logistics; (4) medical care and patient prioritisation; and (5) resource utilisation.

CONCLUSIONS

This study has shown that "table top" exercises using a validated simulation system can serve to guide emergency planners when developing evacuation plans, procedures, and protocols as well in training of all medical staff. The system also served to train adaptive thinking, leadership, communication, and clarification of critical functions.

Hospital preparedness for mass gathering events and mass casualty incidents in Matera, Italy, European Capital of Culture 2019

INTRODUCTION

Mass Casualty Incidents (MCI) may occur during Mass Gathering Events (MGE). A failure to prepare and train the health care system for potential MCI, can cause chaos and delays in the response, leading to an increased morbidity and mortality. Education and training of staff are crucial for preparedness. In Italy, hospital Emergency Plans for Massive Influx of Injured (in Italian designated with the acronym PEMAF) are mandatory since the '90's. However, when available, they are usually poorly known by the staff, rarely reviewed and validated. In 2014, Matera, a city in Southern Italy, was designated as the European Capital of Culture for 2019. As a result, we took this opportunity to revise the "Madonna delle Grazie" PEMAF and to start a program for increasing the awareness of the plan among the medical staff and provide specific training for MCI management.

MATERIAL & METHODS

The PEMAF was reviewed through simulations that involved the entire staff. A partnership with the International Association for Medical Response to Major Incidents & Disasters (MRMI) led to the support of experts and to the organization of residential courses based on the MAss Casualty SIMulation tool (MACSIM®). In total, six residential educational events of MACSIM-PEMAF were organized. Individual capacity was tested before and after the education through self-administered semi-quantitative questionnaires.

RESULTS

All the available resources were mapped and the functional areas identified. Alert, coordination and command sequences were defined. The communication network was improved. Documentation and registration systems were developed. Standard operational procedures (action cards) were created for the key positions. The knowledge and capacity to function in active roles during a MCI was improved among the participants in the educational program.

CONCLUSIONS

MGE are great opportunities for the development of the hosting community but also represent an increased risk of MCI. Preparedness is mandatory for health care systems. The educational format MACSIM-PEMAF seems to be adequate to review and improve the existing plans and transfer specific skills to attendants.
